ABSTRACT:
Disclosed is a washing machine capable of enhancing washing effectiveness by generating a perpendicular-shaped waterflow. The washing machine has a washing tub for providing space to wash washing articles and a pulsator having a plurality of protrusions formed in a concentric periphery with the washing tub, and for forming a perpendicular-shaped waterflow in washing water by the rotation of the plurality of protrusions. The tangling of the washing articles in the center portion of washing tub is prevented, so that the washing effectiveness is enhanced. The washing effectiveness can be further enhanced because the washing articles strike the plurality of protrusions.
